Slow rendering

[alyonapinchuk]

Map (topo style with contour lines) rendering is really slow on iPhone 7.

First of all, thanks for this great app!

I am having this issue too. It's not new, been experiencing this ever since I'm using OsmAnd (~2 years). It also does not always happen, sometimes the rendering speed is fine. Other times however redrawing the map takes minutes or never even finishes. It happens more often when I'm in the backcountry or mountains.

When the app is having rendering issues, the GPS precision often also drops to several kilometers radius. I verified this not being a signal reception problem by switching to other apps which are able to show the position with high precision the same time.

Hardware/software:

• iPhone SE
• iOS 11.4
• OsmAnd 2.1

I created a screen recording of the problem: https://youtu.be/ZR7YE8yyI1w

Same Problem here. Thought it is because my iphone 6 is to slow.

I really love the app. Hopefully it will become more reliable.

We identified the issue is related to SRTM data (the contour lines), we are thinking about possible solutions.

Upvote. I do have the same issue with iPhone 6s and iOS 12. Can confirm that it is most likely the contour lines which render the app barely usable. Especially when zooming close in, the issue is very prominent.

This is very unfortunate, since the App is pretty much outstanding otherwise.

I have the same issue with iPhone 8 and iOS 12.1.4. Very annoying issue.

This was fixed in 2.80 version.
